New findings by researchers UT Southwestern Medical Center are accelerating efforts to eradicate worm infections that afflict a third of the world's population. The new findings, available online and in an upcoming issue of the Proceedings of the National Academy of Sciences, demonstrate that a biochemical system that controls development and reproduction of Caenorhabditis elegans, a common research worm, also provides the same function in several parasitic nematodes, including hookworm. In...

For the first time ever, scientists are using DNA "barcodes" to help prevent the spread of a elephantiasis, an often disfiguring disease that affects roughly one billion people in 80 nations throughout the world. The University of Ghana is pioneering use of the "barcodes", which will be used to map mosquito species in West Africa that spread the disease, also known as lymphatic filariasis (LF). The underlying technology allows scientists to quickly and accurately distinguish species based on...

Trichina worms (Trichinella spp.) are roundworms that can invade a wide range of animals and man. People are most often infected through eating trichina-containing pork. For her doctorate, Rebecca Davidson investigated the incidence of trichina in red foxes in Norway. Her findings show that red foxes throughout Norway are liable to become infected, but that the parasite is most common in southern and especially south-eastern areas. The most frequently-found Trichinella species in the red fox,...

Scientists discover a conserved signaling module controlling the formation of dauer or infective larvae in nematodes 150 years after Darwin's epochal "On the Origin of Species" many questions about the molecular basis of evolution are still waiting for answers. How are signaling pathways changed by genes and by the environment enabling the development of new species? Scientists at the Max Planck Institute for Developmental Biology in Tbingen, Germany, strive to decode the molecular basis of...

LONDON, Oct. 7 /PRNewswire-FirstCall/ -- A study published today confirms that in the ten years since its initiation, the international effort to eliminate lymphatic filariasis (LF) has made unprecedented strides towards ridding the world of one of its most debilitating diseases. The study found that the LF elimination program has prevented 6.6 million children from acquiring LF and stopped another 9.5 million people already infected with the disease from progressing to more debilitating...

North Carolina State University scientists and colleagues have completed the genome sequence and genetic map of one of the world's most common and destructive plant parasites "“ Meloidogyne hapla, a microscopic, soil-dwelling worm known more commonly as the northern root-knot nematode. The research could help lead to a new generation of eco-friendly tools to manage the ubiquitous parasitic worm, which, along with other species of root-knot nematode, causes an estimated $50 billion in...

British and U.S. scientists say nearly 7 million pregnant women in sub-Saharan Africa are infected with hookworms and, therefore, are at risk of anemia. Hookworms are parasitic worms that live in the intestine and can cause a lower than normal number of red blood cells. In a systematic search of medical databases, reference lists and unpublished data, the scientists were able to compare levels of hemoglobin -- the oxygen-carrying part of red blood cells -- according to the intensity of...

By Sahare, K N Anandharaman, V; Meshram, V G; Meshram, S U; Gajalakshmi, D; Goswami, K; Reddy, M V R Background & objectives: Disease burden due to lymphatic filariasis is disproportionately high despite mass drug administration with conventional drugs. Usage of herbal drugs in traditional medicine is quite well known but largely empirical. Hence the present study was designed to screen the in vitro antifilarial effect of four herbal plants on Brugia malayi. Methods: Motility of...

By DIANA MARRERO By DIANA MARRERO Washington -- Nearly a year after dropping out of the presidential race, Tommy Thompson is turning his attention to worms. Thompson, the former Wisconsin governor who later served as the country's top health official, has teamed up with a nonprofit health organization to fight hookworm, whipworm and other tropical diseases that affect 1 billion of the world's poorest people. He says this type of "medical diplomacy" could help build support for the...

Nematology
2013-09-30 13:49:26

Nematology is the study of nematodes, also known as roundworms, which first began in the nineteenth century. Like many fields of study, nematology began with ancient recordings and descriptions lacked elements of modern science. The oldest record of a nematode occurs in the Pentateuch in the fourth book of Moses known as Numbers. The reference, although not plainly stating roundworms or nematodes, is thought to refer to Dracunculus medinensis, a species that is native to the area near the Red...

Trichuris suis
2014-01-12 00:00:00

Trichuris suis is a species of whipworm that is classified within the Nematoda phylum. It can be found in warm tropical regions throughout the world but is rare in arid regions. Males reach an average body length between 1.1 and 1.5 inches, while females reach an average length between 2.3 and 3.1 inches. This species, and other members of the Trichuris genus, was given its common name because of its whip like appearance. The original definitive hosts of this species are pigs, but it is able...

Phasmarhabditis hermaphrodita is a species of roundworm that is classified within the Nematoda phylum. This species is found in soils where slug species from the Limacidae, Arionidae, and Milacidae families are located, with one common host being Deroceras reticulatum. The worm can be located in soil by using real-time PCR testing methods, a test that also distinguishes it from its similar relative, Phasmarhabditis neopapillosa. The life cycle of Phasmarhabditis hermaphrodita begins in...

Onchocerca volvulus
2014-01-12 00:00:00

Onchocerca volvulus is a species of roundworm that is classified within the Nematoda phylum. This species causes the disease onchocerciasis, more commonly known as river blindness. The life cycle of this species is dependent upon an intermediate host, typically the black fly, and a definitive host, which is always a human. Its lifecycle begins when a black fly ingests microfilariae from a human host by consuming blood. The microfilariae that were present in the skin of the human host now...

Trichinella spiralis
2014-01-12 00:00:00

Trichinella spiralis, sometimes known as the pork worm, is a parasite within the Nematoda class. It can be found in pigs, rats, humans, and bears. This worm causes trichinosis in humans, most often from consuming undercooked pork. This species is the smallest within its class, reaching an average body length of .16 centimeters. Females are twice as large as males, displaying a sexual dimorphism. The reproductive organs of females are unique to the species in that the front end holds developed...
